check_netstats.py

Project Notes

I could not find a simple nagios plugin that monitorized all NICs without the use of SNMP. So made this plugin using python and code I found on stack overflow. Data is read from /proc/net/dev with the following possible fields:

recv_bytes, recv_compressed, recv_drop, recv_errs, recv_fifo, recv_frame, recv_multicast, recv_packets, trans_bytes, trans_carrier, trans_colls, trans_compressed, trans_drop, trans_errs, trans_fifo, trans_packets

usage: ./check_netstats.py -i eth0 -p recv_errs -w 100 -c 200

Script also returns data on checked field.
output: eth0 recv_errs OK | [eth0][recv_errs]=0
